(I am breaking my own rule here, because this item is not about maginalised migrants- but I felt it was too important not to publicise as widely as possible. And, indeed, the Australian 457 visa has come dangerously close to producing forced labour Chinese slave labour in Australia )
Change.org reports that the US Department of Labor has released a document about goods that are produced by slave labour- and more goods were found to be made with child labor than forced labor. List of slave-made goods
The most common goods which have significant incidence of forced and/or child labor are cotton, sugarcane, tobacco, coffee, rice, and cocoa in agriculture; bricks, garments, carpets, and footwear in manufacturing; and gold and coal in mined or quarried goods.
Here are some of the worst offenders for forced labor or slavery:
Bolivia: nuts, cattle, corn, and sugar
Burma: bamboo, beans, bricks, jade, nuts, rice rubber, rubies, sesame, shrimp, sugarcane, sunflowers, and teak
China: artificial flowers, bricks, Christmas decorations, coal, cotton, electronics, garments, footwear, fireworks, nails, and toys
India: bricks, carpets, cottonseed, textiles, and garments
Nepal: bricks, carpets, textiles, and stones
North Korea: bricks, cement, coal, gold, iron, and textiles
Pakistan: bricks, carpet, coal, cotton, sugar, and wheat
Note: This doesn’t mean all goods from that sector in that country were produced with exploitation.
